Ingenito, A. (author), Isabella, O. (author), Zeman, M. (author)The need for cost reduction requires using less raw material and cost-effective processes without sacrificing the conversion efficiency. For keeping high the generated photo-current, an advanced light trapping scheme for ultra-thin silicon wafers is here proposed, exhibiting absorptances up to 99% of 4n2 classical absorption limit for wafer...conference paper 2014

Strategy to mitigate the dipole interfacial states in (i)a-Si:H/MoOxpassivating contacts solar cellsMazzarella, L. (author), Alcañiz Moya, A. (author), Kawa, Eliora (author), Procel Moya, P.A. (author), Zhao, Y. (author), Han, C. (author), Yang, G. (author), Zeman, M. (author), Isabella, O. (author)Electrical simulations show that the dipole formed at (i)a-Si:H/MoOx interface can explain electrical performance degradation. We experimentally manipulate this interface by a plasma treatment (PT) to mitigate the dipole strength without harming the optical response. The optimal PT + MoOx stack results in strongly improved electrical...conference paper 2020

Chandra Mouli, G.R. (author), Schijffelen, Jos (author), Bauer, P. (author), Zeman, M. (author)Magnetic cores like powdered iron cores have a variable permeability, which is dependent on the magnetic motive force of the inductor windings. When inductors are designed using such materials, the inductance varies as a function of the inductor current. This causes a non-linear current to flow through the inductor.
